On the Clustering of Bulk Nanobubbles and Their Colloidal Stability [PDF]
Journal of Colloid and Interface Science, 2021 Bulk nanobubbles which are usually observed in pure water have a mean diameter typically around 100 nm. We use a combination of physical and chemical techniques to prove the hypothesis that the nanoentities observed in pure water are stable clusters of much smaller stable nanobubbles.

Stability of Surface and Bulk Nanobubbles
Current Opinion in Colloid and Interface Science, 2021 Abstract The existence of stable nanoscopic gaseous domains in liquids, or nanobubbles, has attracted both skepticism and intrigue since classical theory predicts that spherical gas bubbles cannot achieve stable equilibrium. Can we prove these gaseous domains exist, and if they do, how do they survive?

How Bulk Nanobubbles Might Survive [PDF]
Physical Review Letters, 2020 The existence of bulk nanobubbles has long been regarded with scepticism, due to the limitations of experimental techniques and the widespread assumption that spherical bubbles cannot achieve stable equilibrium. We develop a model for the stability of bulk nanobubbles based on the experimental observation that the zeta potential of spherical bubbles ...

Bulk Nanobubbles, Generation Methods and Potential Applications
Current Opinion in Colloid and Interface Science, 2021 Abstract The existence of nanobubbles, especially bulk nanobubbles, remains a mystery mainly due to their stability and longevity, properties that are investigated by many research groups worldwide. At the same time, high efforts are given to develop new generation methods, and so far, their potential uses have spread to high-value applications. Some

A Deliberation on Nanobubbles at Surfaces and in Bulk [PDF]
ChemPhysChem, 2012 AbstractSurface and bulk nanobubbles are two types of nanoscopic gaseous domain that have recently been discovered in interfacial physics. Both are expected to be unstable to dissolution because of the high internal pressure driving diffusion and the surface tension which squeezes the gas out, but there is a rapidly growing body of experimental ...

On the Existence and Stability of Bulk Nanobubbles [PDF]
Langmuir, 2018 Abstract Bulk nanobubbles are a novel type of nanoscale bubble system. Because of their extraordinary behavior, however, their existence is not widely accepted. In this paper, we shed light on the hypothesis that bulk nanobubbles do exist, they are filled with gas, and they survive for long periods of time, challenging present ...

Bulk Nanobubbles: Production and Investigation of Their Formation/Stability Mechanism
Journal of Colloid and Interface Science, 2020 Nanobubbles (ΝΒs) have attracted concentrated scientific attention due to their unique physicochemical properties and large number of potential applications. In this study, a novel nanobubble generator with low energy demand, operating continuously, is presented.

Research Progress on Bulk Nanobubbles
Particuology, 2022Abstract There are still fundamental problems lying in the basic research of bulk nanobubbles. Are the bulk nanobubbles reported in the literature nano scale bubbles or contaminants in fact? At present, there is not yet sufficient experimental evidence to show that the bulk nanoparticles are only gas bubbles but not other nano scale contaminants.

Ion adsorption stabilizes bulk nanobubbles
Journal of Colloid and Interface Science, 2022The mechanism leading to the extraordinary stability of bulk nanobubbles in aqueous solutions remains an outstanding problem in soft matter, modern surface science, and physical chemistry science. In this work, the stability of bulk nanobubbles in electrolyte solutions under different pH levels and ionic strengths is studied.

Investigating the Existence of Bulk Nanobubbles With Ultrasound
ChemPhysChem, 2016AbstractNanobubbles are expected to dissolve in milliseconds. Experimental evidence of nanobubbles that were stable for days had thus been first received with circumspection. If the large number of experimental confirmations has now made clear that surface nanobubbles could exist, bulk nanobubbles are still subject to debate.
